CLOTHES-WRINGER.

Application filed December 14, 1916.

' To all whom it may concern:

Be it known that I, EDGAR B. STOCKING, a citizen of the United States,residing at Washington, in the District of Columbia, have inventedcertain new and useful Improvements in Clothes-Wringers, of which thefollowing isa specification, reference being had therein to theaccompanying drawing.

This invention relates to certain new and useful improvements inautomatic pressure releasing means for rotating pressing members such asclothes wringers, mangles, and the like, the object being to providemeans for automatically and positively separating the rolls in case ofover feeding of material, injury to the hands of the operator, or theentrance of a foreign object between the same.

Another object of my invention is to provide an automatic releasingmeans in which a mechanism is provided for instantaneously andpositively shutting off the power simultaneously with the operation ofthe releasing means, whereby the rolls are instantaneously separated andthe rotation thereof stopped so as to prevent the foreign object, orother cause actuating the release,

7 from being further drawn between the rolls.

Another and further object of the invention is to provide an automaticpressure releasing device in which the meshing gears of the rotatingpressure rolls are thrown out of mesh simultaneously with throwing offthe power and thereleasing of the pressure in order to allow the clotheswound upon either roll to be unwound therefrom by simply pulling on theclothes thereby overcoming the difliculties now existing in machines ofthis character in having to reverse the movement of the rolls to removethe clothes therefrom.

Another and further object of the invention is to provide a pressure.roll release which is provided with means for manually releasing thepressure whereby the operator can at any time desired instantaneouslyrelease the pressure and shut off the power.

Another and further object of the invention is toprovide a machine whichis so constructed that the same can be operated as an ordinary machineof this character by pro viding means for locking the elements involvedin such positions that the automatic Specification of Letters Patent.

object from being drawn further between the same.

Another object of the invention is to provide an automatic pressurereleasing device in which the rolls can be held in separated positionand the pressure adjusted to enable the machine to wring blankets andother thick goods, the upper roll when the parts are in this positionbeing driven by 'ti' n of the goods passing between the rolls.

Other and further objects and advantages of the invention will behereinafter set forth and the novel features thereof defined by theappended claims.

Like numerals of reference refer to like parts in the several figures ofthe drawings.

In the drawings I have shown my improved construction of automaticpressure release applied to an ordinary wringer comprising a frame 1having slotted side bars 2 provided with bearings 3 in which is mountedthe shaft 1 of the lower pressure roll 5 which is extended as shown at5' and is adapted to be driven by any suitable means as will behereinafter fully described. Mounted in the frame above the lowerpressure roll 5 is an upper pressure roll 6 provided with a shaft 7carrying bearings 8 on which are mounted coil pressure springs 9 engagedby hearing plates 10 carried by a pressure bar 11, said bearings andpressure springs working in grooves formed in the opposing faces of theslotted side bars in order to guide and hold the bearing and pressuresprings in position within the slotted side bars in their verticalmovement therein. The upper ends of the slotted side bars are cut awayto form shoulders to provide a seat for a movably mounted top bar 12which is provided with the usual threaded boxes 13 carrying pressurescrews 14 engaging the bearing plates 10 carried by the pressure bar 11so as to adjust the pressure on the upper pressure roll.

The pressure roll carrying shafts 4 and 7 are provided with the usualmeshing gears 6 at each end of the rolls 5 and 6 inclosed by gearcasings 6 which are connected to the pressure springs by arms 6 in theusual manner.

The walls of the grooves formed in the opposing faces of the slottedside bars are slotted as shown at 15 which slots communicate withvertical bores 16 formed in the side bars at each side of the slot asclearly shown in Figs. 3 and 4. The bearings 8 are provided withdepending lug portions embracing the upper pressure roll shaft 7 havingopenings formed therein through which is adapted to be forced a pin 17which is provided with a cut-out portion 18 forming shoulders forpreventing the longitudinal movement of the pin after the same has beeninserted, the upper edge of the pin being provided with a semi-circularrecess 19 to receive the shaft 7 so as to securely lock the dependinglegs of the bearing in position on the shaft.

In order to provide positive means for raising the upper pressure rollso as to separate the rolls when the pressure is released as will behereinafter fully described, I arrange within the upper portions of thebores 16 contraction springs 20, the lower ends of which embrace theoutwardly projecting end portions of the pin 17 and are seated innotches formed therein and the upper ends carry stirrups 21 throughwhich extend adjusting screws 22 carried by plates 23 mounted on the topof the side bars 2. Arranged within the stirrups on the adjusting screws22 are nuts 24, the corners of which are embedded within the walls ofthe bores 16 so as to prevent the nuts from turning when the screws areadjusted, and it will be seen that by this construction the tension ofthe springs can be adjusted. In order to aid the lifting springs 20 inraising the parts of the wringer arranged above the upper pressure roll,I arrange in the lower portions of the bores 16 expansion springs 25which are pro-- vided with bearing plugs 26 at the upper ends engagingthe ends of the pin 17, the lower ends of the expansion springs 25 beingmounted on adjusting screws 27 as clearly shown in Fig. 3 in order toadjust the tension of the springs.

It will be seen by this construction that I have provided each of theside bars of the wringer frame with expansion and contraction springsarranged to lift the upper pressure roll and the movable parts above thesame when the pressure is released so as to positively separate therolls. In applying the construction to some forms of wringers, I havefound that it is only necessary to employ one pair of springs forraising the upper pressure roll and the movable parts, and I do not wishto limit myself to the use of two sets of springs for accomplishing thisresult as either set can be eliminated and the same result obtained, thetwo sets of springs being only used when my improved construction ofpressure release is applied to avheavy wringer in which the weight ofthe movable members above the upper pressure roll is such that it isnecessary to provide additional means in connection with one set ofsprings to raise the movable parts.

Secured to the ends of the top bar 12 are spring catches 28 carryingbeveled face catch lugs 29 adapted to engage keeper pins 30 extendingacross the slots of the side bars so as to hold the top bar inpredetermined position on the frame in'order to allow the pressurescrews to be adjusted in the ordinary manner for adjusting the pressureon the pressure rolls. Arranged above the keeper pins 30 are stop pins31 adapted to be engaged by the catch lugs 29 in their upward movementwhen they have been thrown otf of the keeper pins 30 so as to limit theupward movement of the top bar and hold the same rigidly within thewringer frame to allow the pressure screws to be adjusted when the rollsare separated so that blankets or heavy clothes can be operated upon asshown in Fig. 7.

Mounted on the outer ends of the shaft 7 of the upper pressure roll 6are operating members 32 and 33 provided with serrated portions 34engaged by the serrated portions 35 of trip members 36 and locked intheir adjusted position by bolts 37, said trip members having inclinedfaces 38 adapted to engage the outwardly projecting curved lower ends 39of the spring catches 28 so as to move said spring catches outwardlywhenbrought into engagement therewith in order to move the catch lugs outfrom under the keeper pins 30 to release the top bar when the pressurerolls are separated beyond the distance of ordinary movement in thepassage of a proper thickness of clothes therethrough. As the upperrolls 6 are separated by a foreign object or by an overthick feeding ofclothes being drawn between the pressure rolls the trip members releasethe spring catches which instantaneously releases the pressure means andthe separating springs lift the upper roll into such position that theforeign object, overfed clothes or hand of the operator are preventedfrom being drawn'farther between the rolls.

From the construction so far described it will be seen that I haveprovided means for automatically releasing the pressure on the pressurerolls and for instantaneously positively separating the rolls.

Mounted on the extended portion 5' of the lower pressure roll shaft 4 isa driving member 40 herein shown in the form of a pulley 40 having a hubportion 41 provided with an annular groove at its inner end as shown at43, the end wall of the groove being provided with a recess 44 adaptedto receive a pin 45 secured in the shaft 4 for locking the drivingmember to the shaft so that the shaft can be rotated through the mediumof the driving member, and I preferably instead of a pulley 40, providethe driving member with a detachable crank as shown in dotted lines at46 in order to allow the machine to be operated manually. The oppositeend of the hub 41 of the driving member 40 is annularly recessed asshown at 47 forming a seat for a coil spring 47' which surrounds theouter portion of the extension 5 of the shaft 4 and is inclosed by a capnut 48 working on the extreme threaded end of the shaft, said cap nutextending over the hub portion in such a manner that the driving memberis free to move longitudinally outwardly. on the extension 5 of theshaft for the purpose hereinafter fully described. The inner end of thehub which is provided with a groove is rounded or bev eled as shown at42 for the purpose hereinafter fully described.

The releasing member 33 is provided with depending legs having enlargedportions 49 provided with inclined faces 50 and fiat faces 51 which areadapted to cooperate with the rolls and at the same time the rolls arefree to rotate independent of the driving member so as to allow clotheswhich may be wound upon either pressure roll to be unwound by simplypulling on the clothes.

As the releasing member 33 is carried upward by the raising of the upperpressure roll the trip member, releasing the spring catches, theinclined face 50 engages the rounded end of the driving member andforces the same outwardly and on the continuous upward movement of thereleasing member 33 the flat faces 51 are brought into longitudinalalinement with the inner end of the hub of the driving member in orderto form a thrust bearing as the driving member continues to rotatethough disengaged from the shaft 5.

In the operation of the wringer as herein shown and described byadjusting thetrip members 36 on the operating members 32 and 33 thedevice can be set so that the trlp members will engage the springcatches and release the pressure before the power is disconnected orthey can be adjusted so that the operating members will be movedvertically a sufiicient distance so as to allow the power to bedisconnected before the pressure is released and I have found inpractice that the best results can be obtained by adjusting the tripmembers on the operating members into such position that in the verticalmovement of the operating members pressure is released, but in eithercase the operation of the pressure release and power control is so closetogether that they are practically simultaneous.

The hub 41 is provided with a threaded bore 52 carrying a set screw 53which can be forced into engagement with the shaft of the lower pressureroll when the clutch pin 43 is out of the seat 44 of the driving memberso as to lock the driving member to the lower shaft in order to enablethe shaft to be rotated when the rolls are in separated position whichallows the wringer to be used for wringing blankets Or other thickgoods.

In connection with the automatlc means for releasing the pressure,separating the rolls and the cutting-off of the power, I providemanually operated means for releasthe power will be disconnected beforethe ing the spring catches which when operated throws the various partsof the machine into the same position in which they are thrown by theautomatic releasing means. The manually operating means consists of apair of pivoted levers 54 and 55 mounted on the side bars 2 of thewringer frame adjacent their upper ends carrying cross bars 56 and 57arranged under the free ends of the spring catches 28 in such a mannerthat when the levers 54, and 55 are oscillated upon their pivots thespring catches will be engaged by the cross bars 56 and 57 so as tothrow the stop lugs out of engagement with the keeper pins 30 whichinstantaneously releases the top bar and allows the lifting springs toseparate the rolls and in the separation of the rolls the releasingmember 33 is carried upwardly by the upper pressure roll shaft 7 so asto bring the inclined faces thereof into engagement with the hub of thedriving member so as to cut off the power. The upper ends of the levers54: are connected together by a chain 58 arranged in a convenientposition to be actuated by the operator of the machine, thus providingprotection from injury as hereinbefore described.

From the foregoing description it will be seen that I have provided anautomatic pressure release and power cut-off which will operateautomatically or can be operated manually, and in connection with amachine constructed as shown and described, I provide means for lockingthe various parts in such position that the wringer can be used. as anordinary wringer so that the manual and automatic means are preventedfrom being operated, and to accomplish this I pivotally mount on theupper end of each of the side bars 2 of the wringer frame a bail 59which is adapted to embrace the ends of the top bar so as to rigidlysecure the top bar in position within the frame in such a manner that itcannot move vertically therein to release the pressure whereby the partsare allowed a slightly free movement with out releasing the pressure orthe cut-off of the power.

In the modification shown in Fig. 8 I show the application of myimproved construction of releasing member for cutting off the power to awringer having outside gears lnclosed in a casing in which 60 indicatesa frame, 61 and 62 the pressure rolls. and 63 the gear casing inclosingthe mesh mg gears not shown. The releasing member 54 carrying the usualtrip member 65 which is provided at its lower end with a returnedbendportion 66 having inclined faces 67 adapted to engage the rounded innerend of the hub portion of a driving member 68 so as to move the drivingmember longitudinally on the shaft in order to throw the clutch pin outof the seat so as to allow the driving member to rotate freely on theshaft.

In the modification shown in Fig. 9, I provide a bearing 70 formed of acasting having integral studs 71 adapted to cotiperate with the springsfor raising the upper pressure roll which construction eliminates theuse of a pin which can be readily placed over the shaft of the upperpressure roll and slid into position within the side bars of the frame.

In the modification shown in Fig. 10, 72 indicates a side bar of thewringer frame having a vertical bore to receive a contraction spring73which is provided at its upper end with an internally threaded sleeve74 held within the convolutions of the spring by friction. Mounted onthe top of the side bar 72 over the bore is a washer 75 through whichextends an adjusting screw 76 working in the internally threaded sleeve7 4: to enable the tension of the spring to be adj utsed.
